Dream House

So I've finally come up with my dream house for when I hit the lotto jackpot...a 3 bedroom home centered around a 10,000 to 15,000 gallon heavily planted freshwater aquarium and has a flat green roof (otherwise known as a grass roof) along with an attached greenhouse.

The setup goes something like this: The overflow drain from the main tank is divided into two flows. The first flow runs under the tank through a 5,000 gallon slow flow gravel bed filter in order for the oxygen to be used up by the aerobic bacteria converting the ammonia from the fish waste first into nitrite and then into nitrate in the first few feet so that the anaerobic bacteria can convert the nitrate into dissolved nitrogen gas in the last portion of the filter. From there it runs into a 5,000 gallon holding tank. The second flow is pumped up onto the roof over a gravel bed under the soil to act as a wet/dry trickle filter, with a sprinkler system watering the top of the soil for 3 hours a day 3 days a week in order to feed and water the grass and help eliminate the dissolved fish waste.. From there it drains down into the 5,000 holding tank. From the holding tank the water is pumped at a rate of 40,000 per hour into the starting point of the tank which is set up as a rock strewn stream flowing into the deeper part of the tank in order to oxygenate the water. A second pump pushes 5,000 gallons an hour through a CO2 reactor and up from under the substrate bed in the deep water to provide both the CO2 and nutrients to the plants, as well as acting as a fluidized bed filter.

The holding tank has a refill sensor to replenish itself if it falls below 1,000 gallons. The rest of the space is to catch rain water draining in from the roof. It rains an average of 2 inches a month through the year where I live which with a 2,000 square foot flat roof should be enough rain water to almost completely cover the amount needed for water changes every month. The water being changed out will be used to water the greenhouse.

Two small hydro-electric turbines under both the aquarium overflow drain and the roof return drain will help off-set the power needed to heat the water, and light capturing skylight domes with mirrored interior walls will help reduce the lighting costs. The green roof is known to reduce the cost of home heating and cooling by as much as 26% and the constant water flow could theoretically increase that to 40% to 50%.

Now I haven't consulted anyone yet and there's been a lot of guess work, but all in all if I'm not too far off in the calculations the cost of building it shouldn't be more than 50% higher than a regular 3 bedroom house and the cost of operations and maintenance should only be a little more than an average home.

So why wait till I hit the lottery to build it? Flood insurance costs :D

The rest of the house keeps chinging in my mind...number of bedroom, garage size, lay out of the kitchen, etc. I was more or less just working out how to have a monster aquarium that funtioned as an environmental control system as well :-)

LOL, DT....yeppa. Definitely fish oriented :-D LOL<br />
<br />
You're not wrong, Sage...since wrting this I've realized I was way off in some places. *shrug* Oh well, a guy can dream ;-) lol

Thanks Queen...if I hit the lotty I'll get you one as well then ;) hehe
